VULCANIZER HEAD.

Application led March 6, 1924. Serial No.,697,238.

The present invention, relating, as indicated, to quick-opening h eadsfor horizontal vulcanizers, is more partieularlydireeted to an improvedhead for use on horizontal vulcanizers in which the head is supported ona movable carriage, allowing it to be first unlocked or released fromthe vulcanizers and then moved out of the plane of the end of thevulcanizer, after which the carriage is moved transversely to bring thehead .out of alignment with the end of the vulcanizer to permit freeaccess to the interior thereof. The heads of horizontal vulcanizers areeX- tremely heavy and must be very strongly supported to maintain them1n locking registration with the end of the vulcanizer proper, and thepresent invention is directed to an improved means for supporting thehead for such purposes. To the accomplishment of the foregoing andrelated ends, said invenproved vulcanizer head; Fig. 2 is also asideelevation showing the means for adjusting the vertical position ofsaid head on its supports;

a front elevation of the vulcanizer and head in C.position thereon; Fig.5 is also a front elevation showing the vulcanizer and head of aslightly modified construction; Fig. 6 is va plan view of the head shownin Fig. 5; Fig. 7 is a side elevation of the head of Figs. 5 and 6; Fig.8 is a view of an improved packing gland for use in sealing the head ofthe vulcanizer; and Fig. '9 is-a side elevation of a modification of theconstruction shown in Fig. 2. l

Referring now to Figs. 1, 2, 3 and 4, there is shown a horizontalcylindrical'vulcanizer l provided with a flange 2 encircling itsouteropen end, which is adapted to receive a circular concave head or endmember 3. The flange 2 is provided with a. series of spaced lugs 4,beneath which are adapted to engage corresponding lugs 5 formed aroundthe peri- Fig. 3 is a plan view of said head; Fig. 4 is.

phery of the coverV 3, the engagement being effected by a partialrotation of the cover after it has been pressed inwardly with the lugs 5between the lugs 4. yThe lugs are so formed on their engaging surfacesthat the head 3 is pressed into the vulcanizer during this engagement,and is securely and frictionally engaged against the inner face of theianged ring surrounding the open end of the vulcanizer. This lockingconstruction is commonly used in horizontal vulcanizers and need not beexplained in greater detail.

The head 3 is of very considerable weight, particularly when made insizes for the larger types, of vulcanizers, and must be securelysupported in such a way as to be freely mow able, both into and out ofengagement with the flanged ring on the vulcanizer, and also out ofposition in front of the vulcanizer so that free access may be had tothe interior for the placing and removal of the rubber goods to bevulcanized. I mount the vulcanizer head on a supporting arm.x 6, securedto a bracket-7 provided with spaced arms 8 and 9, which are aperturedand engage over a shaft 10. The shaft 10 is adjustably supported in asecond bracket, consisting of spaced horizontal arms l1 and 12 connectedby a brace 13, and having spaced ends 14 and 15, throughwhich passes ashaft 16 adjustably mounted, as to its vertical position, in a carriage17, which is best seen in Fig. 4. This carriage' is provided withsupporting rollers or wheels 18 and 19 at its bottom, and with a guideroll or wheel at its top. The wheels 18 and 19 rest upon a rail or track21v and the roller 2Q travels in a channel 22 secured to a series ofbrackets 23, which are suitably mounted to lthe wall in which the press1 is mounted.

g The cover 3 is secured to the arm 6.by means of a trunnion 25 passingthrough the bracket and arm,`and has a slight oscillatory movement withrespect to the arm 6,'depending 7, therebeing adjusting screws 92 forslightly varying the, vertical position of the cover with `respect t0the arm and extension in the same manner as the adjustment described inFig. 2. l

The cover may be locked either in its open or closed position by meansof a notched arm provided with recesses or notches 34 and 35. By liftingthe member 33 the cover may be swung to the desired position, eitherlocked or unlocked, when the arm is swung downward,'causing one of thenotches 34 or 35 to engage over a rib 36 formed on the top of theextension 28 of the bracket 7.

The bracket 7 is secured at 'the desired height on the shaft 1() bymeans of.bolts 38 and 39 passing through the arms 8 and 9 on the bracket.and engaging against thisshaft, while the vertical position of theshaft may be adjusted and fixed by means of an adjusting bolt or screw40 passing through the'lower arm 12, and bearing against the lower endof this shaft 10. In the manner described the positio-n of the cover,that is both its vertical height and the plane in which it stands, maybe completely adjusted to bring the cover into perfect parallelism andlregistration with the flanged locking ring VAon the press The secondbracket is similarly adjustably secured to the shaft 16 by means ofadjusting screws 41 andv 42, and the position of this Shaft is adjustedand fixed by means of an adjusting screw 43 engaging against the lowerend of this shaft.

I' Inoperation, the cover, if in locked position, is remo-ved from thepress 1, first lifting the locking member 33, then rotating the coverout of engagement with the lugs o-n the fianged ring, this movementbeing conven- "iently executed by inserting a bar in one of the twoangle members 45Im0unted opposite 4each ether adjacent the outer edge ofthe cover, after-which the cover is swung away 1 vfrom-the front of thepress a short distance.

l to the interior. l ordinarily a battery of presses are employed,

-The carriage 17 is then pushedto the side 0f the vulcanizer members,the door being carried bodily out of position in front of the press and.allowingcomplete'and free access It will be understood that mounted.parallel 'to each .other with their ends in the same plane, andthetracks 21 and 22 may extend along the front of the entire j In Figs. 5,6 and 7 I have shown a modi-l fied construction in which the carriageconsists of a bowed frame 50 provided with a ,vertical support 51thereon, the wheels 52 for the carriage being mounted in the lower partof the spaced legs 50, w'hile the upper or guide wheel 52 is mounted onthe upper end of the member 51. In this constructionv the cover 53 iscarried on the end of a threaded shaft 54, passing vthrough a`. suitablyformed boss 55 on the -vertical member 51 and operated by means of ahand wheel 56.

By turning Athe wheel-56 the shaft 54 oper-- ates to advance the cover53 toward the flanged ring on the end of the press er to move it awayfrom the same, and after the cover has been moved out of the plane ofthe ring on the end of the press the carriage may be shiftedtransversely to displacethe cover from in front of the' vulcanizer.

The same means for locking the cover to the press are here employed, butthe vertical position of the carriage and of the cover are secured byadjusting screws 57 engaging against the axles on which the lower wheels52 are carried, and by other screws 59 engaging against opposite sidesof the axle, on

lwhich the guide roll 52 -is carried. By adjusting these various screwsthe vertical postion of the carriage, and particularly of the verticalmember 51, may be adjusted to bring the plane of the cover parallel tothat of the flanged locking ring 60 on the end of the press.

' Mounted above and below the center of the j `,screw shaft very mucheasier for the operator and preventing it fr om wearing unduly as wouldbe the case were the entire weight of the cover supported on this shaft.

In Fig. 8 I have shown 'a combined pressure and suction packing gland,which may be Yused with either of the' two types of covers here shown,or in fact, with otherv covers if desired. This packing'gland isin theform of a Y-shaped strip 70 provided with arms 71, 72 and 73. The arm 73is received in a recess 74 in the fianged ring 75, which is mounted ontheend of the press, and which carries the 'usual locking lugs 76. Thearms 71 and 72 of liu The particular advantages of the cover and.

the mount-ing therefor which are here shown are that they can be used ina restricted space Where there is very little head room in front,

of the vulcanizer presses, as is often the case in factories Where thesepresses are employed. Furthermore, by mounting the covers on carriagesthey can be bodily moved out of the Way when it is desired to charge ordischarge the press, the same tracks serving for all of the presses, andall of the carriages on which the heads or covers are mounted.

Other modes of applying the principleI of vmy invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by an of the followingclaims or the equivalent o such stated means be employed.
